Sunday will probably become changeable again, with heavy showers or longer spells of rain arriving, particularly in the north and west. However, parts of the southeast are likely to stay mainly dry with some sunny spells. It will be windy at times, especially in the north. On Monday a band of cloud and rain may sink southwards across the country, with brighter conditions following on behind. Into the following week, there remains a lot of uncertainty, although we could continue to see spells of wet and windy weather, particularly in the northwest. It will be drier in general across the southeast, although there is a risk of some thundery showers here at times. Temperatures will probably be near normal, though perhaps rather warm at times in the south.

During this period, we are most likely to see changeable weather conditions featuring across the United Kingdom. However, there will be some dry and fine weather at times too. On balance spells of rain and strong winds are likely to dominate in the north and west, with drier and brighter weather more common in the south and east. Temperatures will probably remain close to normal for the time of year in most parts, though they may become warm or very warm at times in the south which may generate some thunderstorms.
